Les routeurs industriels sont connectés par l'intermédiaire des données du réseau cellulaire, et conviennent donc mieux aux environnements extérieurs et commerciaux intérieurs. Il n'est pas nécessaire de prendre en compte le problème du câblage. Ils ont seulement besoin de signaux stables et plus le...

Computer technology has been with us since the mid-20th century. However, the technology behind the Internet of Things has been mature since Tom, Dick and Harry all started using PCs. Telemetry science, the earliest representation of the Internet of Things,…

What is serial communication? The academic explanation is a method of continuously sending one bit of data through the bus at a point in time. Just like an archer shooting his bow and arrow frequently, whoosh, whoosh, whoosh… What is…

RS-232C, RS-422A, and RS-485 are communication standards of EIA (Electronic Industries Association). Among these communication standards, RS-232C has been widely used in various applications and even as standard equipment on computers, and Often used. Used to connect to serial servers…

In serial communication, data is sent one bit at a time over a signal line, so in order for the receiving end to receive the data accurately, the sending end must know the sending data for each bit.在RS232中，同步已经定义了

The LoRaWAN network architecture is deployed in a star topology (as opposed to a mesh topology, such as Zibgee). The base station of a LoRaWAN network laid out in a star topology relays data between sensor nodes and network servers.…

Among the EIA standard series, the RS485 protocol is considered the most versatile, showing good performance in all four standards of serial communication. This is the reason RS485 is widely used as a communication interface when multiple nodes need to…

Different application scenarios Switch: Mainly used in internal core access, internal data exchange, and more commonly used in LAN; Router: It is a network outlet, mainly responsible for interconnection with operators, and is more commonly used to connect to external…

What is RS232 protocol? The RS232 protocol is a popular serial interface used to connect computers to networked devices such as serial servers. We will look at the serial port pins used to implement RS232 and some other reference information…

The 4g module is a cellular communication device that uses two standards, TD-LTE and FDD-LTE, and is loaded into a designated frequency band. The software supports the basic circuit set of the standard LTE protocol and is an IoT communication…

In order to make the transmission of networking equipment such as industrial routers, DTUs, and serial servers more stable, these devices will be equipped with anti-surge, anti-static, anti-pulse and watchdog protection. Among these hardware protections, there is one that can…

Starting from the analysis of NB-IoT Internet of Things technology, it introduces the physical layer of the NB-IoT system and its coexistence with other systems, introduces the LTE system and GSM system, and analyzes the necessity of research on their…
